The green diamond holds a singular place in the world of gemmology. In many cultures, green evokes prosperity, harmony and nature. In fine jewellery, it is synonymous with exception.
A Unique Mechanism: Irradiation
Unlike other colour diamonds whose tint comes from chemical impurities (nitrogen, boron), the green diamond owes its colour to a physical phenomenon: irradiation by uranium rays. During its formation or journey to the surface, the carbon crystal is exposed to natural radiation that modifies its electronic structure and gives it its characteristic hue.
This phenomenon is extremely rare in nature and very difficult to reproduce in a controlled way in the laboratory. This is why high gem-quality green diamonds remain among the most difficult stones to obtain, whether naturally or artificially.
The Dresden Green Diamond
Among historic green diamonds, the Dresden Green is the most celebrated. Discovered in India in the 18th century, it originally weighed approximately 119 carats before being cut into a pear shape of almost 41 carats. It belonged for a long time to the Polish King Frederick August II and is today housed in Dresden, Germany, where it is considered a national treasure.
The Symbolism of Green in Jewellery
Green is a colour laden with meaning. In the Middle East, women traditionally wear many green stones, and this colour is particularly celebrated during certain periods such as Ramadan. In Europe, it is associated with nature, growth, and hope.
A green diamond on the finger is not merely a piece of jewellery — it is a statement, an affirmation of absolute singularity.
